Vortex Phases in Condensed Matter and Cosmology

Placing a high-Tc superconductor in an increasing external magnetic field, the flux first penetrates the sample through an Abrikosov vortex lattice, and then a first order transition is observed by which the system goes to the normal phase. We discuss the cosmological motivation for considering the electroweak phase transition in the presence of an external magnetic field, the analogies this sy...

Exponential law as a more compatible model to describe orbits of planetary systems

  According to the Titus-Bode law, orbits of planets in the solar system obey a geometric progression. Many investigations have been launched to improve this law. In this paper, we apply square and exponential models to planets of solar system, moons of planets, and some extra solar systems, and compare them with each other.

String defects in condensed-matter systems as optical fibers.

We analyze the core structure of string defects in various condensed matter systems, such as nematic liquid crystals and superfluid helium, and argue that in certain cases the variation of the refractive index near the core is such that it can lead to total internal reflection of light travelling along the string core. These strings thus behave as optical fibers providing a qualitatively new ap...

Non-equilibrium Phase Transitions in Condensed Matter and Cosmology: Spinodal

These lectures address the dynamics of phase ordering out of equilibrium in condensed matter and in quantum field theory in cosmological settings, emphasizing their similarities and differences. In condensed matter we describe the phenomenological approach based on the Time Dependent GinzburgLandau (TDGL) description. After a general discussion of the main experimental and theoretical features ...
